Is Your 3.7L Grand Cherokee Running Rough?
If you’re dealing with frustrating issues like stalling at stoplights, a persistent check engine light with baffling codes, or a vehicle that simply refuses to start, the problem often points directly to a failing Engine Control Module (ECM). As the brain of your 2005-2006 Jeep Grand Cherokee 4×4, a faulty ECM can cause a cascade of problems that are notoriously difficult to diagnose. I’ve seen it countless times in my shop: mechanics and owners chase their tails replacing perfectly good sensors, only to find the core issue was the computer all along.
This isn’t just a replacement part; it’s a direct solution. We take the guesswork and frustration out of the repair by providing a professionally prepared ECM, part number 5094898AD, that arrives at your doorstep ready for immediate installation. No trips to the dealership, no expensive programming tools needed. We handle the critical software flashing for you, using your vehicle’s specific VIN and mileage to ensure perfect communication between the module and your Jeep’s systems.
Real-World Diagnostic Story: “A customer’s 2006 Grand Cherokee came in last week with a no-start and a P0688 ASD relay control circuit code. They had already replaced the relay twice, assuming it was a simple fix. After a quick check with my multimeter, I found the ECM wasn’t providing the necessary ground to activate the relay. The original computer had an internal failure. Installing one of our pre-programmed modules restored the circuit, and the Jeep fired right up. It’s a classic scenario for these vehicles.”

Plug-and-Play Installation: No Dealer Visit Required
You can perform this installation in your own driveway with basic hand tools. The ECM is located in the right-hand (passenger side) rear of the engine compartment. Follow these steps for a smooth installation:
- Safety First: Disconnect the negative terminal from your vehicle’s battery and secure it away from the post to prevent accidental contact.
- Locate the ECM: Open the hood and find the module mounted on the passenger-side firewall, near the rear of the engine.
- Disconnect the Wiring: Carefully release the locking tabs on the electrical connectors. There are typically three main harnesses. Pull the connectors straight out without wiggling to avoid damaging the pins.
- Remove the Old Module: Unbolt the mounting hardware that secures the old ECM to the firewall. Keep the hardware, as you will need it for the new unit.
- Install the New ECM: Mount your new, pre-programmed module in the same location using the original hardware.
- Reconnect and Secure: Firmly plug the wiring harnesses into the new ECM until they click into place. Ensure the locking tabs are fully engaged.
- Power Up: Reconnect the negative battery terminal. Your Grand Cherokee is now ready to start with its new brain fully integrated.
